Diagnosis and management of hematopoietic cell transplant-associated thrombotic microangiopathy (TA-TMA) are very complex and controversial, given multiple ongoing issues and comorbidities in sick transplant recipients. Complement activation via classic and alternative pathways is emerging as a potential pathogenetic mechanism in the development of TA-TMA. Complement-centric diagnostic strategy using functional and genetic tests may possibly support diagnosis, enhance molecular understanding and direct drug development...

The interactions between magnetic skyrmions and structural defects, such as edges, dislocations, and grain boundaries (GBs), which are all considered as topological defects, will be important issues when magnetic skyrmions are utilized for future memory device applications. To investigate such interactions, simultaneous visualization of magnetic skyrmions and structural defects at high spatial resolution, which is not feasible by conventional techniques, is essential. Here, taking advantages of aberration-corrected differential phase-contrast scanning transmission electron microscopy, we investigate the interaction of magnetic skyrmions with a small-angle GB in a thin film of FeGe1-xSix...

A networked control system (NCS) is a control system which involves a communication network. In NCSs, the continuous-time measurement is usually sampled and quantized before transmission. Then, the measurement is transmitted to the remote controller via the communication channel, during which the signal may be delayed, lost or even sometimes not allowed for transmission due to the communication or energy constraints. In recent years, the modeling, analysis and synthesis of networked control systems (NCSs) have received great attention, which leads to a large number of publications...

The group of new oral anticoagulants or NOACs, now termed direct oral anticoagulants or DOACs, with their favourable results from large scale phase III clinical trials, represent a major advancement and expanded armamentarium in antithrombotic therapy. Dabigatran, rivaroxaban, apixaban and edoxaban are now in clinical routine use for prevention and treatment of arterial and venous thrombotic diseases as addressed in their clinical trials. Usage of the DOACs is expected to increase as clinicians gain more experience and reassurance with data from the real world studies which are generally consistent with that from clinical trials...

BACKGROUND: The Doctor of Nursing Practice (DNP) degree positions nurse practitioners (NPs) and other advanced practice registered nurses, with clinical competencies similar to other disciplines requiring doctoral education (medicine, physical therapy, psychology, and pharmacy). In addition, all these disciplines also offer residencies. However, nursing is the only discipline that does not require a doctoral degree and/or have a systematic approach to residency training for advanced practice roles...

In recent years, metal-organic frameworks (MOFs) have been employed as heterogeneous catalysts or utilized as solid precursors for synthesis of catalytic materials. However, conventional MOFs and their derivatives, which normally have relatively large particle sizes, exhibit limited mass transfer and modest catalytic activities owing to lengthy diffusion path and less exposed active sites. On the other hand, it has been generally conceived that nanoscale MOFs will be beneficial to materials utilization as well as to mass diffusion, but the instability of nano-MOFs poses a serious issue on their practical applications...

Size-exclusion chromatography coupled with SAXS (small-angle X-ray scattering), often performed using a flow-through capillary, should allow direct collection of monodisperse sample data. However, capillary fouling issues and non-baseline-resolved peaks can hamper its efficacy. The UltraScan solution modeler (US-SOMO) HPLC-SAXS (high-performance liquid chromatography coupled with SAXS) module provides a comprehensive framework to analyze such data, starting with a simple linear baseline correction and symmetrical Gaussian decomposition tools [Brookes, Pérez, Cardinali, Profumo, Vachette & Rocco (2013 ▸)...

In these days of political vagueness, to use a kinder term, although many would describe the situation as turmoil, in Europe, there are success stories to be lauded. Notwithstanding the direction individual countries choose in relation to closer or not so close co-operation in Europe and the direction the political agenda will travel over the next few years, I believe science and in particular medicine has benefited enormously form close co-operation across the European Union and with colleagues outside this political and trading block of nations...

Future prospects continue to be strong for research using the rat as a model organism. New technology has enabled the proliferation of many new transgenic and knockout rat strains, the genomes of more than 40 rat strains have been sequenced, publications using the rat as a model continue to be produced at a steady rate, and discoveries of disease-associated genes and mechanisms from rat experiments abound, frequently with conservation of function between rats and humans. However, advances in genome technology have led to increasing insights into human disease directly from human genetic studies, pulling more and more researchers into the human genetics arena and placing funding for model organisms and their databases under threat...

Vitamin K (phylloquinone or vitamin K1 and menaquinones or vitamin K2) plays an important role as a cofactor in the synthesis of hepatic blood coagulation proteins, but recently has also aroused an increasing interest for its action in extra-hepatic tissues, in particular in the regulation of bone and vascular metabolism. The accurate measurement of vitamin K status in humans is still a critical issue. Along with indirect assays, such as the undercarboxylated fractions of vitamin K-dependent proteins [prothrombin, osteocalcin (OC), and matrix gla protein], the direct analysis of blood levels of phylloquinone and menaquinones forms might be considered a more informative and direct method for assessing vitamin K status...

The Convention on the Rights of Persons with Disabilities (CRPD) requires States to replace their mental health laws based on substitute decision-making for persons with mental health issues with laws based on the supported decision-making paradigm. However, the exact scope of the CRPD's mandates is currently under debate, especially in the case of persons with very high support needs. The Mental Health Care Bill, 2013, introduces supported decision-making in India in the form of advance directives and nominated representatives...

Complementary and integrative treatments, such as massage, acupuncture, and yoga, are used by increasing numbers of cancer patients to manage symptoms and improve their quality of life. In addition, such treatments may have other important and currently overlooked benefits by reducing tissue stiffness and improving mobility. Recent advances in cancer biology are underscoring the importance of connective tissue in the local tumor environment. Inflammation and fibrosis are well-recognized contributors to cancer, and connective tissue stiffness is emerging as a driving factor in tumor growth...

The aim of this paper is to systematically evaluate a biased sampling issue associated with genome-wide association analysis (GWAS) of imaging phenotypes for most imaging genetic studies, including the Alzheimer's Disease Neuroimaging Initiative (ADNI). Specifically, the original sampling scheme of these imaging genetic studies is primarily the retrospective case-control design, whereas most existing statistical analyses of these studies ignore such sampling scheme by directly correlating imaging phenotypes (called the secondary traits) with genotype...
